Report #104389

[architecture] Should I use SQLite or Postgres for my single-server web app?

Start with SQLite for simpler ops, lower cost, and no separate server. Only switch to Postgres when you need multiple concurrent writers \(more than ~5-10\), complex queries requiring advanced indexing, or need to scale horizontally. SQLite is perfect for SaaS prototypes, internal tools, and low-concurrency applications.

Journey Context:
SQLite is embedded, zero-config, ACID, but has limitations: only one writer at a time \(WAL allows concurrent reads\), no user management, no network access, and limited concurrency. Postgres requires a server but offers better concurrency, extensibility, and replication. A common mistake is jumping to Postgres for every project, adding operational overhead. For a small team with a single app instance, SQLite is often sufficient and easier to deploy.
